High-pole lamp

Abstract

The invention relates to a high-pole lamp is provided with an approximately elliptic projection region and is good in radiation effect. The high-pole lamp comprises an LED (light emitting diode) light source, a driving power supply, a lamp body, lamp heads and light-reflecting covers, wherein the lamp body is made from sectional material blocks and is provided with radiating fins; the light-reflecting covers are arranged in the lamp heads; two sides of the section of the lamp body are of a drum type and are provided with bulged arc lines; the lamp body with a drum-type section is internally provided with a ladder-shaped groove which is used for connecting the lamp heads; the radiating fins are arranged at the two sides and top of the lamp body; and the top of each lamp head is in contact with the top of the ladder-shaped groove. The high-pole lamp provided by the invention has the advantages that the whole profile of the lamp is of a rectangle, and the lamp heads are arranged in parallel, thus the illumination region is of an ellipse shape, and the lamp is suitable for occasions requiring large illumination regions such as ports, a railway goods yard and the like; in order to improve the heat sink effect, three faces of the lamp body are provided with the radiating fins, and the tops of the lamp heads are in contact with the top of the groove in the lamp body, thus forming a 'thermocontact' effect; and internal-auxiliary radiators are arranged among the lamp heads and at the outer side of the outmost lamp head, and the radiation among the lamp heads is strengthened.

Description

technical field [0001] The invention relates to a high-pole LED lamp with high brightness and large-area illuminance, in particular to a high-pole lamp applied to occasions requiring high brightness and large-area lighting such as ports, docks, and construction sites. Background technique [0002] In ports, docks, stadiums, airports, freight yards, construction sites, etc., it is necessary to use lamps with strong lighting capabilities. The current high pole light generally refers to a new type of lighting device composed of a steel column light pole above 15 meters and a high-power combined light frame. It is composed of lamp holder, internal lamp electrical, rod body and basic parts. Most of the internal lamps are composed of floodlights and floodlights. Most of the light sources are high-pressure sodium lamps with a power of more than 400W, and the lighting radius is up to 60 meters. But the biggest problem of this kind of lighting fixture is that it consumes a lot of e...

But the biggest problem of this kind of lighting fixture is the large energy consumption

[0003] With the development of semiconductor lighting technology, LED light sources are widely used in the above occasions. In order to ensure the illumination requirements, it is necessary to use several LED light sources to form a surface light source for lighting. Difficulty, especially in high altitudes, there are many safety problems; second, light distribution is difficult, and its effective lighting radius is difficult to guarantee

At present, LED integrated light sources have been widely used, but the biggest obstacle to the application of this new product is that there is no efficient heat sink solution during use
